Install the battery (see
The VX 680 terminal uses a Li-ion smart battery (see
Documentation for ordering information). The internal logic of the smart battery
prevents both overcharging and undercharging (a fault condition in which the
battery level goes well below the minimum acceptable charge and the battery
becomes unusable).
The terminal will operate on battery power or on power pack power. The
VX 680
smart battery charger in the terminal will be active whenever the power pack is
connected.
The following are features of the smart battery:
•
Two Li-ion cells
•
A fuel gauge module that:
•
monitors state of charge (voltage and percentage of capacity),
•
communicates with the terminal (charge parameters and status),
•
determines full charge capacity (on charge cycle and uninterrupted
discharge cycle), and
•
automatically shuts down when cell voltage is extremely low.
•
A safety circuit that:
•
prevents cell damage from overcharge, over-discharge, or overheating,
and
•
activates when the battery is left in an unused terminal for extended
periods.
